Question 34 1 pts The population distribution of number of close friends in Canada is symmetric with mean of 6.5 and a standard deviation of 9.5. A researcher, unaware of these values, plans to randomly select 18 individuals and use the sample mean to estimate the population mean number of close friends. What is the sampling distribution of the population mean? 0 Approximately Normal with mean 6.5 and standard deviation of 9.5. 0 Approximately symmetric with mean 6.5 and standard deviation of 2.24. 0 Approximately Normal with mean 6.5 and standard deviation of 2.24. Q We cannot determine the sampling distribution due to the sample size. 0 Approximately symmetric with mean 6.5 and standard deviation of 9.5
